Used as an intermediate in the synthesis of vat dyes, particularly for producing blue and green shades in cotton and other cellulosic fibers. It contributes to the formation of anthraquinone-based dye structures that offer good lightfastness and wash resistance. Also employed in the production of disperse dyes for polyester and in some cases as a photoinitiator in polymer chemistry due to its ability to absorb UV and visible light. Its role in organic synthesis extends to the development of functional dyes for technical applications, including electronics and photochemical devices.
